I have a 2000 ford focus zx3 Zetec. After driving for a while and I am at s top light the car sometime swill almost stall and my battery light will comeone for like half a second....

What could this be. Already cleaned MAFS, Throttle body, new air filter, and did a tune up....[mad]

the coil pigtail? alternator going bad? the tube at back of the intake manifold

I was looking at my engine closer and on the PCV I see that the hose is kinked. Can that be the main problem? Its the hose

check your 02 sensors... That can do exactly that.

I kinda had that same problem. took it to autozone and had them test the battery and it came back to the alternator going bad, wasn't charging the battery only had like 35% charge to it.
